Help me to solve this simple problem
find a if
fx = 2x^3 - ax^2 + 2x - 7
has a repeated factor
find a if
fx = 2x^3 - ax^2 + 2x - 7
has a repeated factor
What is repeated factor? Does it mean that it has two or more same roots? (Its translation problem)
Have you tried Rational Roots Theorem and synthetic division? Picking rational roots to try will not immediately involve 'a'. The synthetic division will certainly involve 'a'. The use of synthetic division either gives remainder of zero for a root or a nonzero remainder if a choice is not a root.
